may we be curious and ask what the new project is ?

 Not allowed to say just at the moment Dave due to legal gagging but I will post something when I can for sure.

Thanks Gareth. You didn't rate the Sodium Hydroxide idea we discussed earlier?

Thanks Rob. I did consider overloading the fuel balance to render any dried residue ineffective and as you rightly say, using a hygroscopic diluent to see that it struggled to dry at all - I was thinking Calcium Chloride.

Also thought about introducing a reducing agent, say Magnesium, to reduce the Chlorate and create an inert Oxide but have safety concerns on this one although if wet I can't see it cooking off to ignition point - the atmosphere might be a bit fruity of course!

Yes, volume in litres is all that's required.

Nothing to do with IR. One is an obscurant, one is a signal - to hide the operator or to display a signal he wishes to transmit.

Duration varies according to the specification, density generally strives to achieve.
